Having seen HH live a few times and in possession of a good few of his albums, each one markedly different from the last, I must confess to writing this as a convert.This is not the subtle version of the artist by any means. If you are looking to put your feet up and chill out to delicate, melodic music this will not do. So grab a caffeine boost and play this loud. It's percussive and disrespectful of convention but blows the cobwebs away with ease. Think what 'Sorcerer' is to the rest of Miles' catalogue and you're on the right lines.
I have seen this album around for a while tempting me to buy it but I have so many really solid jazz albums from this era that I do not get enough time to listen that I gave it a miss. I finally relented after seeing it recommended in the Rough Guide and I am not disappointed, The rhytmic settting for these tunes is brilliant with Hancock and the band assembled here on top form. There are also excellent liner notes that put this session into perspective and claims that the unseen guiding hand of Mile Davis is at work, helping Herbie choose the musicians for instance. The setting of the tunes is not startling particularly after such a long time, but there are some genuine momets of magic and I would recommend this to anyone exploring this area of music
